In general, the invention provides a magnetic head device and linear tape drive that widen the high frequency side of the servo range. In particular, the invention provides a magnetic head device comprising a magnetic head chip with multiple magnetic elements arranged for recording or playback of multiple tracks and a fine positioning structure that uses a bimodal construction that may widen the high frequency side of the servo range by increasing the resonant frequency of the magnetic head chip including the tracking structure and lowering the Q value of the resonance point. In addition, the invention includes a damping structure suitable for the fine positioning structure that improves high speed response by widening the range in which the magnetic head device can be used for a servo. The magnetic head device may use a linear tape drive method.

An improved flat cymbal is formed from a flat sheet of stainless metal by laser cutting it into a selected form, such as a Maltese Cross having four arms with spaces between the arms. An opening is formed in each of the four arms. The cymbal will produce a distinctive sound that may be modified or tuned by changing the size of the openings or inserting jingles, rivets, sizzlers or shrapnel in the openings in the arms.

Method and apparatus for guiding a moving tape having a tape edge parallel to a direction of motion of the tape wherein the tape is received tangentially on a curved surface having an edge. Force applied to the tape is increased as the tape drifts farther away from a nominal position so as to move the tape away from the edge of the surface. Lateral motion of the tape is dampened by breaking up an air-cushion between the tape and the curved surface.

Methods and arrangements are provided for use in a printer and associated computer(s). The printer is configured to periodically and/or automatically detect when changes are being made to a print media supply tray and output/display the current configuration of the print media supply tray for use by the user and/or programs running on the computer. The current configuration of the print tray is determined using detectable mechanisms that are either hardware and/or software implemented. The configuration of the supply tray is displayed to the user via the printer display, a tray-mounted display, and/or though a graphical user interface (GUI) on the computer. The configuration is defined by at least the size and type of the print media associated with the supply tray.

The invention involves a novel method and structure for utilizing homeotropic vertically aligned nematic liquid crystal cells in the production of high contrast microdisplays. Two circular polarizers are used in order to propagate circularly polarized, rather than planar polarized, light through a liquid crystal cell. The use of circularly polarized light eliminates the liquid crystal director alignment requirements for the transmittance of light necessary for planar polarized light. With no director alignment requirement, it is possible to use perfectly homeotropic vertically aligned nematic cells irrespective of domain size and shape because fringing field induced director tilt will not decrease the transmittance of the liquid crystal cell.

A packaged die (112) for an integrated circuit (62) that eliminates the wire bonds required in the prior art, and provides integrated circuit packaging while the circuit (62) is still in a wafer format. A wafer substrate (64) on which the integrated circuits (62) have been fabricated is patterned and etched to form signal and ground vias (74, 72) through the substrate (64). A back-side ground plane (82) is deposited in contact with the ground vias (72). A protective layer (90) is formed on the top surface (76) of the substrate (64), and a protective layer (98) is formed on the bottom surface (84) of the substrate (64), where the bottom protective layer (98) fills in removed substrate material between the integrated circuits (62). Vias (106) are formed through the bottom protective layer (98), and the wafer substrate (64) is diced between the integrated circuits (62).
